Yes.

I now tried a couple of boots in a row and one of them actually succeeded (with
glxgears and own OpenGL applications). But the other times it got stuck during
boot, though not always before the switch to native resolution. One hanged with
some systemd error (rfkill stuff). I will try to get more information. But it
looks like there may be a couple of problems or everything is just a symptom of
some deeper one. Which still is strange is that the symptoms disappear when I
switch to the Intel card or Optimus in the BIOS. Maybe some ACPI problems and
nothing directly related to nouveau.

Sorry for bothering you with that :-). I guess you should close the bug and if
I find something related to nouveau I'll open a new one.
